Thomas Gleixner 1cfd68496e [PATCH] Fix cascade lookup of next_timer_interrupt
When searching for the next pending timer in the timer wheel we need to take
the cascade into account.  The current code has several problems:

 1. it looks into the previous cascade
 2. it ignores a pending cascade
 3. it ignores multiple cascades

Change the cascade lookup, so it calculates the array index from the point of
the next cascade and always look at the cascade buckets, when the cascade is
pending, i.e.  gets executed in the next timer softirq.  When multiple
cascades are pending, then lookup the next buckets too.
